waarna HEATER.

Application led August 25, 1921. Serial No. 495,271.

To all 'whom t may concern.'

Be it known that I, GEORGE F. PAUL, a citizen of the United States, residing at Los Angeles,in the county of Los Angeles and a State of California, have invented a new and useful Improvement in a Water Heater, of which the following is a specification.

My invention relates to water heaters, and more especially to what is generally i0 known as an auxiliary water heater for use in connection with a boiler.

My improved device is so constructed that it may be readily secured in an opening made in the front plate or wall of the boiler l preferably below the water-line so that the walls of the circulating passages of my de-v vice will be submerged in the hot ,water in the boiler so as to heat the water in my device to a temperaturedesirable for domestic and other uses.

-The apparatus is so constructed that it is prac ically a unit that requires but a small amount of labor to install, and therefore is capable of being set up by inexperienced persons, or by skilled mechanics in a comparatively short time. Also, my water heater requires no special tools in installing thesame, and its structure is such that several units may be readily connected together by a@ piping or nipples when a greater quantity of hot water 1s desired. A further object of my invention is to provide a structure which is both economical in construction and of added'eiiiciency in operation in that the partition hereinafter mentioned may be much more cheaply manufactured than round pipe and may also be provided of less thickness thereby facilitating the heating of the water during its passage through the device.

I prefer to carry out my invention in substantiall he manner hereinafter more fully described, and as particularly pointed out in the claims. Reference'will now be made to the -accompanying drawings that form a part hereof, in which- Y Figure 1 is a central longitudinal section of myheater showing it installed upon a fragmental portion of a boiler.

of umts for lncreasing the quantity of water heated. v

In the drawings similar reference characters are employed to designate the same parts in the lseveral views, and by referring,

rst, to Figure 1,'it will be seen I,4 may make 70 use of the hand cleanout, or I form an opening 10 in the front plate 11 of the boiler in a horizontal plane preferably below the water level and above the crown sheet or the tubes 12 thereof, and through this open- 75 ing 10 is passed the tube of my improved heater, as will be hereinafter more fully explained. y

The main portion of my` deviceconsists of a hollow casting that comprises a cylir.- drical hollow casing 13 the end of which is flanged, as at 14, to provide a flat plate for mounting uponplate 1.1 around the opening and secured; 1n position by-boltsfrlvets or the like. The flanged end of casing 13 is 85 internally threaded to receive the threaded outer end ofa tube 15 that is closed at .its opposite end, as seen in Fig. 1, and prior to securing the structure I prefer to place a suitable packing or gasket 16 that com- 90 presses into the space between tube 15 and plate 11 when the structure is tightened into position. A

The ca'sing13- extends out from the boller .plate 11, as seen in Fig. 2, and its upper segment is provided with an upright dlscharge stub 17 that is internally threaded to receive the lower end of the hot-water discharge pipe 18, the axis of whichis transverse or at a right angle to the axis of cas-iI ing 13. Depending from the under segment of casing 13 is a cylindrical embossment 19, the axisof which is horizontally disposed and intersects the axisof casing 13, as seen in vFigures 1 'and 2. The interior of this 195 embossment communicates with the interim-- of the casing through a neck o r restricted passageway 20 (Fig. 3), and vlts' opposite ends are interiorly threaded to receive, re-

spectively, a closure plug 2l and the supply pipe 22. t

ln order to keep the currents ot water separated or continnousin both directions in tube 15 and casing i3, l. have employed a partition 23 of V-shape in cross-section that is inverted when placed in the tube and which extends to near' the inner end ot tube 15, as seen in Fig. l of the drawings. 'lhe forward end of the partition 23 extends into the casing where it straddles neck 20 and it terminates in substantially the transverse plane of an annular shoulder 2a in the casing. rl`he manner oit securing the partition is to provide lateral tlange's 25 upon its outer end to which is suitably secured a metal or other disk 28 that fs wider than the bore ot casingsl so that one ot its surfaces bears againstthe outer tace ofshoulder 2d thereby closi the-end of the partition as well and the outer portion ot the casing and prevents the interniixging ot the cool and ot streams or currents ot water. ln order to secure the structure just described in rigid relation to the casing, llv internally thread the outer end. ot said casing bach to shoulder 2t and screw therein a suitable lug 29 until it bears against dish 28 thereyretaining the same in position. By removing plug 29 the dish may be grasped and thereby draw out partition 23, all oit which will be derstood by reference to Fig. l oit the drawings.

For ordinary domesticpurposes only a single. unit is necessary, but when eater quantities oil hot water are desired may make a lurality ot holes in the boiler alining horizontally and connect two or more casing; or units by nipples 30, as seen in Fig. ot the drawings, the ends out the nipples being secured intothe opposite ends or embossment i9 thereby forming a battory, it being understood each casing is provided with its respective tube l5 that extends into the boiler and is submerged in the water therein.

ln o eration, the water to be heated enters throng supply pipe 22, passing troni embossment 19 through neck 20 and into pipe l5 between the walls ot partition 23.

flllie head under which thevwater is supz plied causes its circulation inwardly through the V-shaped channel 23 and' baclrwardly.

around the exterior ot the' sides ont thev parti- A tion to discharge ipe i8, and during its circulation inwar y through the partition andoutwardly between the walls ot the partition and tube l5A it is heated by innction from the surrounding heated water or steam contained in the boi erl ln order to position the V-shaped partel trop 23 in assembling the structure, ll proier rorina notch or recess @d the upper segrl :ment or .2e the neonati apex ot the partition will tit when the latter is inserted into tube 15; this notch also preventing any relative rotative movement ot disk 28 when the plug nut 29 is being screwed into tight position.

While l. have herein illustrated and described the preferred manner of carrying out my invention, it ot' course will be obvious that immaterial modications may be made to the construction and arrangement of the parts without departing from the principle ll have disclosed, and ll, therefore, desire it understood that such changes are fully contemplated as coming within the scope of the appended claims.
